j IMPROVEMENT IN SPRINGS FOR VEHICLES.

Specification forming part of Letters Patent No. 154,816, datedSeptember 8, 1874; application filed June 19, 1874.

To all whom it may concern:

Be it known that I, THOMAS H. Woon, of New York, in the county of NewYork and State of New York, have inventeda new and useful Improvement inCarriage-Springs, of`

` were granted to me on the 27th day of May,

1873, No. 139,348; and has for its object to prevent, in' a side/-barwagon, the carriage body from crowding the upper set of springs incontact with the reach.

My present invention consists in making the upper set of tr-ansversesprings (those which are above the side bars) U-shaped, so

that one arm and end of each of these springs will be secured tothe-side bar, and the other to the carriage-body. This constructionrequires the use of four such upper springs, and causes an open spacetothe left between them above the reach, so that they can never becrowded in` contact with said reach.

In the accompanying drawing, the letter A represents the front axle, andB the hind axle, of a half-spring wagon. C and D are the twoupwardlybowed semielliptic springs, which rest on and are secured to theaxles A and B, respectively. The ends of the springs G D connect withthe side bars E E, as shown. F F F F are four U-shaped springs, of whichtwo are secured with their lower ends to each of the two side bars, theupper ends of all being fastened to the carriage'body G. Suitable clipsor other fastenings may be used to secure the springs F to the sidebars. The length of the springs F is such that they do not reach acrossthe space between the side bars, but leave an open space between them,so that, if the wagon-body is depressed, it cannot crowd said springsupon the reach. Moreover, the springs F can be produced at a less costthan the semi-elliptic upper springs described in my aforementionedLetters Patent, and give fully the same degree of strength.

The same invention will apply `when the springs C D are dispensedwithand the side bars directly connected to the axles.

I clailn as my invention- The U-shaped transverse springs F F, incombination with the side bars E E and wagon-body G, substantially asand for the purpose described.

Trios. E. woon.
